Hello. I also have a 14 month old. He eats 3 meals and 2 snacks a day. He is on whole milk, not formula so I don't know if that changes anything. I am also lucky that my son loves most everything but I used to have a hard time thinking of meal ideas also. I try to go by a loose rule of protein/veggie/fruit almost every meal...Hope these ideas help!
Breaksfast : Oatmeal, yogurt, cinnamon raisin toast, cheese toast, scrambled egg, cheese grits, cottage cheese, fruit.
Morning snack: cheerios or some other dry cereal, cereal bar, graham crackers, fruit, cheese.
Lunch: Quesidillas (you can hide veggies and meat in these if your children don't like veggies/meat), Turkey and cheese sandwich (i heat it for a few seconds in the microwave so its easier to chew), tuna fish (mixed with a little mayo, messy but he loves it), cheese cubes, veggies, fruit, macaroni and cheese, tofu
Afternoon Snack: same options as morning snack
Dinner : he usually eats the same thing as we do. Fish, chicken, hamburger, ravioli, pasta, veggies, chicken pot pie, casseroles, rice, etc.......
I let him try everything, just cut it up into bites for him. I just stay away from things i don't think he can chew, like meats besides ground hamburger or chicken.
I hope these ideas helped!
